How to build .so file on windows for the google/nearby Connections API?

[Kirti2489]

Hi Everyone,

I have been trying to build google/nearby Connections API using the Bazel build system on my Windows machine. I am trying to generate a .so file from this so that I can include it in my android app.

When I build using the following command without making any changes to the code, I am getting a core.lib file: -

bazel build -s --check_visibility=false //connections:core --spawn_strategy=standalone --verbose_failures

To get a .so file as output, I have a genrule to the BUILD file under nearby/connections : -

genrule(
name = "coreshared",
srcs = [":core"], # Refer to the cc_library
outs = ["coreshared.so"],
cmd = "cp ./$(location core) ./$(location coreshared.so)",
)

This does generate coreshared.so under bazel-bin/connections, but when I try to consume the generated .so file from the Android app I am getting an error- ld.lld: error: 'coreshared.so' is neither ET_REL nor LLVM bitcode

I am sorry if there is something very obviously wrong in my approach 😅, I am very new to both Bazel and Android. Can someone please help me in pointing what I am missing here?

Thanks for your time in advance.
